Bluetooth 4.0 and LCD monitoring: check voltage, capacity, and battery health straight from your phone or the built in display.
IEC 62619 certified LiFePO4 cells: the safest lithium chemistry going around, with no risk of fire or explosion.
4000+ charge cycles: outlasts AGM and lead acid batteries by years, so you're not replacing it every season.
Deep discharge performance: holds voltage under load for more usable power when you actually need it.
5 year manufacturer's warranty: backed for the long haul, not just the first trip.

Installation

This battery is a drop in replacement for most AGM and lead acid setups using M8 pole and Anderson terminals. Confirm your tray or compartment matches the slimline dimensions before fitting. Connect according to your system's wiring diagram, matching polarity carefully. For dual battery or multi battery bank setups, professional installation is recommended to make sure your BMS, charging source, and wiring are all compatible. A straightforward single battery swap usually takes under an hour, while dual battery or multi bank setups can take longer depending on your system.
